That's the second time you made reference to two I/O Lincs. Only one is required. Yes, the I/O Linc can send a message for each state (i.e., powered, not powered). In any case, if the PLM is not powered, then Insteon signals are not received. I haven't found a Z-Wave equivalent (both NO and NC contacts).
You'll need one Open/close sensor for each of power cut and power restored. But, that'll work only of the I/O Linc is powered from the utility only, not the generator
